Editing Byzantine fault (section)

==== Applications and Examples of Byzantine Fault Tolerance in Blockchain ====
'''Safety Mechanisms:''' Different blockchains use various BFT-based consensus mechanisms like Practical Byzantine Fault Tolerance (PBFT), Tendermint, and [[Delegated Proof of Stake (DPoS)]] to handle Byzantine faults. These protocols ensure that the majority of honest nodes can agree on the next block in the chain, securing the network against attacks and preventing [[double-spending]] and other types of fraud. Practical examples of networks include [[Hyperledger|Hyperledger Fabric]], [[Cosmos Blockchain|Cosmos]] and [[Klever blockchain|Klever]] in this sequence.  

'''51% Attack Mitigation:''' While traditional blockchains like Bitcoin use Proof of Work (PoW), which is susceptible to a [[51% attack]], BFT-based systems are designed to tolerate up to one-third of faulty or malicious nodes without compromising the network's integrity.

'''Decentralized Trust:''' Byzantine Fault Tolerance underpins the trust model in [[Decentralization|decentralized]] networks. Instead of relying on a central authority, the network's security depends on the ability of honest nodes to outnumber and outmaneuver malicious ones.

'''Private and Permissioned Blockchains:''' BFT is especially important in private or permissioned blockchains, where a limited number of known participants need to reach a consensus quickly and securely. These networks often use BFT protocols to enhance performance and security.
